Method Detail

getInstance

public static ZonedChronology getInstance(Chronology base,
                                          DateTimeZone zone)

Create a ZonedChronology for any chronology, overriding any time zone it may already have.

Parameters:

base - base chronology to wrap

zone - the time zone

Throws:

java.lang.IllegalArgumentException - if chronology or time zone is null

getZone

public DateTimeZone getZone()

Description copied from class: BaseChronology

Returns the DateTimeZone that this Chronology operates in, or null if unspecified.

Overrides:

getZone in class AssembledChronology

Returns:

DateTimeZone null if unspecified

withUTC

public Chronology withUTC()

Description copied from class: BaseChronology

Returns an instance of this Chronology that operates in the UTC time zone. Chronologies that do not operate in a time zone or are already UTC must return themselves.

Specified by:

withUTC in class BaseChronology

Returns:

a version of this chronology that ignores time zones

withZone

public Chronology withZone(DateTimeZone zone)

Description copied from class: BaseChronology

Returns an instance of this Chronology that operates in any time zone.

Specified by:

withZone in class BaseChronology

Parameters:

zone - to use, or default if null

Returns:

a version of this chronology with a specific time zone

getDateTimeMillis

public long getDateTimeMillis(int year,
                              int monthOfYear,
                              int dayOfMonth,
                              int millisOfDay)
                       throws java.lang.IllegalArgumentException

Description copied from class: BaseChronology

Returns a datetime millisecond instant, formed from the given year, month, day, and millisecond values. The set of given values must refer to a valid datetime, or else an IllegalArgumentException is thrown.

The default implementation calls upon separate DateTimeFields to determine the result. Subclasses are encouraged to provide a more efficient implementation.

Overrides:

getDateTimeMillis in class AssembledChronology

Parameters:

year - year to use

monthOfYear - month to use

dayOfMonth - day of month to use

millisOfDay - millisecond to use

Returns:

millisecond instant from 1970-01-01T00:00:00Z

Throws:

java.lang.IllegalArgumentException - if the values are invalid

getDateTimeMillis

public long getDateTimeMillis(int year,
                              int monthOfYear,
                              int dayOfMonth,
                              int hourOfDay,
                              int minuteOfHour,
                              int secondOfMinute,
                              int millisOfSecond)
                       throws java.lang.IllegalArgumentException

Description copied from class: BaseChronology

Returns a datetime millisecond instant, formed from the given year, month, day, hour, minute, second, and millisecond values. The set of given values must refer to a valid datetime, or else an IllegalArgumentException is thrown.

The default implementation calls upon separate DateTimeFields to determine the result. Subclasses are encouraged to provide a more efficient implementation.

Overrides:

getDateTimeMillis in class AssembledChronology

Parameters:

year - year to use

monthOfYear - month to use

dayOfMonth - day of month to use

hourOfDay - hour to use

minuteOfHour - minute to use

secondOfMinute - second to use

millisOfSecond - millisecond to use

Returns:

millisecond instant from 1970-01-01T00:00:00Z

Throws:

java.lang.IllegalArgumentException - if the values are invalid

getDateTimeMillis

public long getDateTimeMillis(long instant,
                              int hourOfDay,

Description copied from class: BaseChronology

Returns a datetime millisecond instant, from from the given instant, hour, minute, second, and millisecond values. The set of given values must refer to a valid datetime, or else an IllegalArgumentException is thrown.

The default implementation calls upon separate DateTimeFields to determine the result. Subclasses are encouraged to provide a more efficient implementation.

Overrides:

getDateTimeMillis in class AssembledChronology
